Adcom GFA 535 II

Above advice prolly good if you are at the searching stage,buuuut if you already own this amp then you can extract more PRAT and low end by doing a few things.Have a good power cord put on it,being captive will require some surgery.Add dynamat to ringy parts of the chassis.Get some cones under it onto a good solid shelf.Also add a box with weighting to top,adjust contents to help tune it.Not too much dynamat or weight.Upper treble would need mods internally which would be waste of $$$.The points I covered here can be done on the cheap and make it more useful. If you shop and aquire a second amp you can run the Adcom on low end duty.

A used PS Audio 2C or 2C Plus or the Elite Integrated Amplifier is a much better choice than the adcom for about the same money; ie, 150/175. The Sound Well in Berkeley has an inspected and warrantied 2C for 200; worth the extra money as you get a 6 mo warranty.

I've an gfa535II and I like it. Can I upgrade it with a second gfa535II bridged both in mono?

Thanks

I'm running a gfa-535 II with Elac B6 and it's a great match. Keep in mind that everything is relative to price point. It certainly outperforms what was available at that price point (epsecially with the used price of the Adcom) by a margin. Loads of bass, very listenable and informative highs, good detail and a nice pace. Not quite as dynamic as others might be but not "just" listenable. It's enjoyable and it makes me want to listen to my music.

I love a 13 year thread gap. I've owned a few 535s, both original and version II and they're bulletproof little monsters that sound amazing. I have a 5300 (85 watts per side or something) that I chose to keep over a 535II since I simply like the 5300's tone a little more. I use it as a secondary amp driving little deck designated speakers (KEF Q10s) I stick in my windows to cover the deck sound needs, and that 5300 works amazingly. Cost about 150 bucks used in mint shape maybe 5 years ago. Note that back in the day I went for the late 80s "death of the receiver" Adcom tuner/preamp/535 thing with Vandy 1Bs…great combo.
